I had the Look Junior SPX 10 B100 bindings fitted to my new K2 Fullofit skis for powder conditions in Japan. I'm a small lady, so the Junior bindings were a good choice for my frame. I found the heel lever release mechanism in a difficult position, too far away from my upper body as compared with my Marker bindings on all mountain skis. As a small person, I often did not have the strength to use my pole to release from my bindings; instead, I kept my ski on and used my entire body weight to be able to release from my initial ski, then just used my boot to release the second ski.
